Description

Transmission method and user terminal

This application claims the priority of the Chinese Patent Application, filed on Jan. 04,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

Technical field

The present application relates to the field of mobile communications technologies, and in particular, to a transmission method and a user terminal.

Background technique

A mobile communication system refers to a system in which a service provider provides communication services for a user terminal (such as a mobile phone) by deploying a wireless access network device (such as a base station) and a core network device (such as a Home Location Register, HLR). . Mobile communication has experienced the first generation, the second generation, the third generation, and the fourth generation. The first generation of mobile communication refers to the original analog, voice-only cellular phone standard, mainly using analog technology and Frequency Division Multiple Access (FDMA) access method; second generation mobile communication introduced Digital technology, improved network capacity, improved voice quality and confidentiality, "Global System for Mobile Communication" (GSM) and "Code Division Multiple Access" (CDMAIS-95) Representative; third-generation mobile communication mainly refers to CDMA2000, WCDMA, TD-SCDMA three technologies, all using code division multiple access as access technology; the fourth generation mobile communication system standards are relatively unified internationally, for international Long Term Evolution/Long Term Evolution-Advanced (LTE/LTE-A) developed by the 3GPP, the downlink is based on Orthogonal Frequency Division Multiple Access (OFDMA), and the uplink is based on single carrier frequency. Single Carrier-Frequency Division Multiple Access (SC-FDMA) access method, flexible Bandwidth and adaptive modulation and coding scheme, the downlink peak rate reached 1Gbps, up peak rate of 500Mbps high-speed transmission. Based on the LTER13 LAA downlink transmission method, MulteFire newly defines the uplink transmission method and can work independently on the LTE technology of the unlicensed band, that is, stand-alone LTE-U. In the transmission process of the unlicensed band, the channel access specification of the band is to be observed. For example, the unlicensed band of 5 GHz needs to be Listened Before Talk (LBT), that is, the channel needs to be detected before being idle. Only allowed to send. In the traditional LTE, the base station-centric centralized scheduling is adopted. For the uplink transmission of the UE, the scheduling request needs to be initiated first, and then the uplink scheduling of the eNodeB (evolved Node B, eNB) is waited for the transmission, and each time the signal is sent. The eNB or the user equipment (UE) that is the transmission module needs to perform the LBT. Therefore, the traditional eNB-based uplink transmission is in the transmission of the unlicensed frequency band in terms of delay or LBT success probability. This can lead to performance degradation such as upstream throughput and latency, especially when sharing channels with Wi-Fi devices based on distributed scheduling.

Aiming at the above-mentioned shortcomings of the uplink transmission based on the base station scheduling, the MulteFire proposes a UE-based autonomous scheduling uplink transmission method, that is, Autonomous UpLink (AUL) or Grant-less UpLink (GUL), which allows The UE initiates uplink transmission autonomously, reducing the delay and the number of LBTs.

In the process of implementing the present application, the inventors found that at least the following problems exist in the prior art:

In the existing base station scheduling-based transmission, the Cat-4LBT is performed by the base station. After the channel access is successful, the eNB transmits the downlink signal and schedules the UE to transmit the uplink signal in the corresponding maximum channel occupation duration (MCOT). For the autonomous scheduling uplink transmission method, the UE can use the Cat-4LBT and successfully contend for the channel, and then obtain the uplink transmission corresponding to the current channel access parameter, and within the MCOT, the UE can perform the autonomous scheduling of the UE. Since the autonomously scheduled uplink transmission is not completely controlled by the eNB, the subframe configured by the autonomously scheduled uplink transmission cannot be the same as the downlink subframe and the uplink subframe in other transmissions. Therefore, the available resources for autonomously scheduling uplink transmission are limited. Therefore, the transmission efficiency of the autonomously scheduled uplink transmission is low.
